OIL-BURNER.

Speci'cati'onof Letters Patent. Patented J an, 27, 1914, Applicationfiled September 22, 1913. Serial No. 791,250. l

This invention relates to new and useful;

improvements in oil burners and is designed to provide a device of thecharacter described for utilizing kerosene and other similar :fuel andfor conveniently and effectively converting the same into gas under theheatthe Vburner itself.

Another object is to provide for taking the gas'from the generator andcarrying the same to the burner proper, where combustion takes place, ina simple and efficient manner.

Anotherv object of the invention resides in the provision of a fuelnozzle andaneedle valve for controlling the passage of fuel being soconstructed that by its operation it cannot enlarge the nozzle orificeand thereby permit the flow of too much fuel therethrough. V l

With the above and other objects in view, the invention has particularrelation to cer- 'tain .novel features, of construction, operation andarrangement of parts, anexample of which is given in this specificationand drawings,

Figure 1 is a sectional sideelev-ation of theburner, Fig. 2' is asectional side eleva- 'i tion of the nozzle, showing the connectingparts, and Fig. o shows the burner in inverted position, showing alsothe fuel-tank and the service pipe connected therewith.

Referring now more particularly to the drawings, wherein like numeralsof reference designate similar parts in each of the figures, the numerallrefers to a horizontal cylindrical shell or casing generator of theburner and is provided at its inlet or rear end with a reducer 2 whichis screwed tliereover to partially close said end and is provided with acentral internally threaded perforation 3.

The numeral 4 refers to a conical shaped nozzle, the enlarged end ofwhich is externally threaded and screwed into the inner end of theperforation 3 and the inner en of which projects into the generator 1.This nozzle has a longitudinal passageway 5 therein, which is conical inshape. A valve and useful which forms the v of the casing 7, so that byrA suitableservice" vided with an elbow- 14,

d nipple v 6 is provided which is outwardly threaded at each end, andone end of which is screwed intothe outer end of the perforation 3.Screwed on to the other end of this nipple is the valve casing 7 andextendi'ng through said casing reduced, forming the annular shoulder,19, said reduced end conforming in shape tothe passageway 5' andcontrolling theft fuel therethrough. The outer end needle .valve 8 hasthe hand wheel 10";iii intermediate section thereofj is" threaded,through a correspondingly ed portion "turning the. hand wheel 10 theneedle valveumaybe controlled. Ipipe 11 istconnected to the nozzle andis in communication with a source of supply-as, for example,1an elevatedtank 12 located at a as to preclude the possibility of the ignition ofthe oil in said tank.` A suitable control to control the supply ofliquid fuel to the nozzle.

The forward end of the generator is proone end of Which is secured overthe said end of said generator and the other end of which receives thebushing 15.

he which 'is secured in the the other end of which one end of the burnerpipe 17 is secured so as to bring said burner pipe parallel with thegenerator 1. The other end of this burner pipe is closed by means f thecap 18 which is secured thereover. The burner pipe is provided withorifices 19, positioned in the side thereof toward the generatorA gas isdesigned to escape in the form of a fiame. y

In the operation of the device, oil is admitted to the 'interior of thegenerator 1 through the nozzle 4, said oil collecting in thevgenerator 1. Heat is then 'applied to the generator in any preferredmanner, so as to convert the oil into gas, which will pass through thebushing 15 and the L 16 to the burner 17 and-through the perforations 19numeral lvrefersto an L, one end of I thereof where it may be ignited bymeans of a match or votherwise soas to emit flames y d which strike thegenerator so as to maintain said generator in `a heated condition tocontinue the formation of gas.

Particular attention is called to the formadistance from the burner, so

bushing 15 and in 1, through which the and nipple, is the y v -needlevalve 8 whose inner end is abruptlyl -valve 13 is carried bythe servicepipe so as specific `'construction and it is pointed out the -fact thatthe annular shoulv er 9- of the valve is arranged to-abut against theouter vend of the nozzle 4, when the valve .is com-- preventsV the pointof Athe 'valvefrom gradually venlargxng .the passageway in the nozzleand pletely closed. .This construction thus permitting too much fuel totlow into the generator 1.

In case t oo :auch oil is admittedinto the` generator, 1t will not becompletely' gasiied vand sootfwill -be formed' in said generator; and inaddition tothe soot formation there will be the, liability shownobviates these defects and provides foi-,the complete and exact.control'ofI the How-of Jfuel through the'nozzle and into thegenerator.'i` f -f `.While no specific application-.tof

althoughD ity may be used to generate heatufor any purpose whatsoever,

VVinvention, it is apparent-that the specific1 construction thereof`While I have shovvn only one form of the mayf be' varied to suitthejditferent applications lof the burner aric'l A v i l y vsageivay iscpxnpl ely closed by said valve,
